Abstract
We proposes and experimentally demonstrates a RF/FSO fusion transmission system under smoke channel. First, an RF and laser-integrated communications payload is designed for RF/FSO fusion links to achieve mutual information backup for both FSO and RF links. Coupled optoelectronic oscillator (COEO) can generate 10.0 GHz low-jitter optical pulses and 10.0 GHz low-phase noise RF signals simultaneously. The measured RF side-mode rejection ratio is 52.16 dB, and the phase noise at 10 kHz offset is about −117.6 dBc/Hz. The experimental results show that COEO has good compatibility in RF/FSO fusion communication and effectively solves the problem of RF/FSO link compatible sharing. Then, we established a RF/FSO fusion transmission system based on a COEO. Taking the complexity of the smoke channel, the RF/FSO link is not switched to achieve simultaneous transmission communication without interruption. The power jitter, signal-to-noise ratio, and bit error rate of RF/FSO links are investigated for different smoke visibility and is further investigated. The experimental results indicate, the fusion RF/FSO system is more reliable under extremely dense smoke conditions based on a COEO, which is significant for the future development of reliable space high-speed information transmission and networking.
期刊介绍:
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
